Idea for a Node Red flow

KD0RC Member, Super Elmer Moderator

I just got a cheap transverter from the Transverters Store, and so far it is working great. I really love that I can now see the whole 2 meter band on the panadapter. Going to a frequency by clicking on the desired signal works pretty well, but then I need to tune around to get to the exact frequency.

It dawned on me that spots could be used as a quick way to see which repeaters are active, and even better, a click on the spot will take me straight to the frequency. The only downside is that the CTCSS tone will not be set using this method. To mitigate that, I put the tone frequency right in the spot.

Here is a snippet of C++ code that I used to test this out:

sendResult = send(sock, "CD1 | spot add rx_freq=146.700 callsign=W0DK_BARC_100", 54, 0);

sendResult = send(sock, "CD2 | spot add rx_freq=146.310 callsign=KB0VJJ_CRA_123", 55, 0);

sendResult = send(sock, "CD3 | spot add rx_freq=146.520 callsign=Simplex", 48, 0);

sendResult = send(sock, "CD4 | spot add rx_freq=144.200 callsign=144.200", 48, 0);

sendResult = send(sock, "CD5 | spot add rx_freq=145.340 callsign=N0PQV_Evgn_103.5", 57, 0);

sendResult = send(sock, "CD6 | spot add rx_freq=146.760 callsign=W0IA_BCARES_100", 56, 0);

Here is the result:

Now I can see which repeaters are available, which are active and quickly navigate to them. A txt file with the spot info in it could be read in and sent to the radio as spots. I will fool around with this a bit from the C++ perspective, but I thought with Dave's Node Red dashboards, it might be desirable to include something like this to help round out the application.

So Dave, any thoughts on this?

    Hi Len

    There is someone on the Node Red group that was already taking spot info and sending to the radio via Node Red. It wouldn’t be difficult to us a DX cluster filter to filter only entries you want and do what you want.

    you can create buttons in Node Red for favorite repeaters and have those send frequency, mode, CTCSS, and offset to the radio.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
